I appreciate the comments and conversation concerning my project
. There are currently two tanks with a capacity of 70 gallons each (total of 140 Gallons). The current
tanks are baffled so lining would require removal
of the baffles (at least two per tank; that is all I can see from the inspection
port). The tanks seem to have a leak about a 1/3 of the way from the bottom. The removal
of the tanks is a job that has been started. It required removing the teak
and holly sole to gain access. The tanks are glassed in to the bilge
I would think that replacement tanks would require baffles but I'm not an expert (obviously). After the comments made on this forum and reading other web sites, it seems that fiberglass may not be the best idea.
Thanks for the help. The size and complexity of this job raises the stakes and the right decision on the replacement material is important.
